Fenner Lake
Fenner Lake is mostly located in the Town of New Chester, Adams County, WI. It is a mesotrophic natural seepage lake with fair to very good water quality and very good clarity. The lake has 33 surface acres, with a maximum depth of 30 feet and an average depth of 5 feet. The water level of Fenner Lake has been dropping in the last few years. A study is currently underway to determine causes. Fenner Lake has been designated a no-motor lake for some years. There is a sand boat ramp and swimming area at the far east end of the lake, owned and maintained by Marquette County. There is a Fenner Lake Association.
